URL: https://github.com/apache/superset/issues/13290
Hi,
I had a dashboard with few charts that were working as expected. Then I went
ahead and added a line chart (which had empty result) into the dashboard which
crashed my dashboard and I see the below error. Please note that this issue
exists only in one of the dashboard, all other dashboards loads fine.
### Expected results
expected to load the dashboard
### Actual results
Sorry, something went wrong
500 - Internal Server Error
